Regulation of leaf senescence by reproductive sink intensity in cowpea vigna unguiculata l. walp


, : Regulation of leaf senescence by reproductive sink intensity in cowpea vigna unguiculata l. walp. Annals of Botany (London) 61(6): 655-658

The relationship between seed number per pod and senescence of the leaf in its axial was examined in a determinate cowpea (Vigna unguiculata L. Walp) variety C.779. The seed number per pod was reduced at all fruiting nodes by surgical excision of part of the 4-d-old pod. Leaf senescence as measured by loss of leaf area, chlorophyll content and soluble protein was slowed down in leaves supporting the development of an artificially reduced number of seeds. Diminished nitrogen mobilization from the leaf could not account for the reduced rate of leaf senescence. The result suggests the involvement of a senescence signal from the developing seeds to the leaf in its axil. Development of the basal half of the excised pod in the cowpea provides a unique system for manipulating seed number per pod.
